Check that your unit is a GMAX II 7900 (Standard/ProContractor/Lo-Boy) equipped with an Endurance Vortex MaxLife pump (generally 2014+). Cross-check with your serial number and parts manual for final confirmation.
QuikPak arrives pre-assembled and pre-oiled, reducing install time, mess, and stack-up errors. It helps ensure factory correct compression and sealing for longer service life.
No special tools are typically required—basic hand tools and adherence to your sprayer’s service procedure are sufficient. Always depressurize and follow safety instructions.
Worn packings commonly cause leakage and pressure fluctuations. Repacking with 17H840 often restores performance; however, also inspect piston/rod and check valves for wear.

Ordered the 17H840 Pump repair kit (17H840) for our crew - it matched the original spec exactly, down to the part number. Would order again without hesitation.
